+===== Other methods to create 100% CPU load =====
+<code bash>
+yes > /dev/null &
+</code>
+**NOTE:**  This only imposes 100% load on a single core.
+To impose this against multiple cores, then run the command multiple times to exhaust all the CPU power:
+<code bash>
+yes > /dev/null &
+yes > /dev/null &
+yes > /dev/null &
+yes > /dev/null &

+===== Another method to produce 100% CPU load usage =====
+<code bash>
+dd if=/dev/zero of=/dev/null
+</code>
+To fully utilize all the cores on your system, run the following command:
+<code bash>
+fulload() { dd if=/dev/zero of=/dev/null | dd if=/dev/zero of=/dev/null | dd if=/dev/zero of=/dev/null | dd if=/dev/zero of=/dev/null & }; fulload; read; killall dd
+</code>
+<WRAP info>
+**NOTE:**  The number of the above command in the function should be equal to the number of cores (for example 4 in this case).
